Immubots

Immubots are nanobots which live a sapient's bloodstream to protect the host from disease and monitor their health internally. Their programming can be updated by a doctor through access via the wristpatch.

Immubots come in different variations from different sources. Some are high alert, ready for anything out of the box, while others keep known viruses and diseases at bay but are not species-specific enough to cater to all species' needs.

Others are bought illegally and as a result can be badly programmed, not passing shuttleport checks and other scanners. It is implied that these can be fixed, but having non-GC approved immubots is regarded as risky.
